AndroidJavaException：java.lang.ClassNotFoundException：com.google.unity.ads.UnityInterstitialAdCallback

Question

我將 Admob 添加到我的游戲中，我的測試廣告在 Unity 編輯器上完美運行，我沒有收到任何錯誤。 但是，當我為我的 android 設備構建時，廣告沒有顯示，我收到此行的錯誤消息：

您的構建中似乎缺少 class。 您是否解決了所有 android 依賴項？ 簽入 Assets -> Plugins -> Android googlemobileads-unity.aar 文件的文件夾。 如果此文件不存在，則執行以下操作。

嘗試在 Android Resolver -> Force Resolve 中強制解析 android 依賴。 它將包含您構建中的所有文件。
